Original application filed December 3, 1920, Serial No. 428,020. Dividedand this application filed December 17, 1921.

To all whom it may concern Be it known that I, CHARLES E. MCCOY, citizenof the United States, residing at Logansport, in the county of Cass andState of Indiana, have invented certain newand useful Improvements inWashing Machines, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to improvements in washing machines and thisapplication is a division of my application No. 428,020 filed Dec. 3,1920.

The primary object of the present invention is to furnish a light,strong, inexpensive pounder for use in pounder type washing machines.

Another Object of the present invention is to furnish an improvedpounder formed generally of sheet metal and constructed to preventtearing of the articles being washed.

Another object of the invention is to provide an improved pounder whichmay be readily cut from sheet metal and inexpensively assembled, so thatthe pounders may be manufactured in a factory where sheet metal articlesare made.

With the foregoing objects outlined, and with other objects in viewwhich will appear as the description proceeds, the invention consists inthe novel features hereinafter described in detail, illustrated in theaccompanying drawings and more particularly set forth in the appendedclaims.

Referring to the drawing:

Figure 1 is a perspective view of my improved pounder.

Fig. 2 is a side view of the same.

Fig. 3 is an end view.

In the drawing, 1 designates a plurality of sheet metal angle ironsarranged in parallel relation but with their horizontal portions 2directed in opposite directions. Connected to these angle irons are aplurality of channel shaped sheet metal crossbars 3, the longitudinaledges 4 of which are curled or bent backwardly on themselves to providecurved surfaces at the edges of the channel shaped members. Arranged ineach of the channel shaped members is a lining bar 5 preferably of wood,and the lining bars and channel shaped members are Serial No. 523,008.

connected to the angle irons 1 preferably by means of bolts 6. Threechannel shaped members are shown in the drawing but it is obvious that agreater or less number may be employed for different sized. machines.

In operation the pounder is reciprocated by means of a bar 7 and itfunctions to force the article being washed downwardly in the washingmachine tank. During this operation, the water in the tank flowsupwardly into the spaces 7 provided between the sides of the channelbars and the sides of the liner bars 5 and this water workslongitudinally of the channel bars and finally is ejected at the ends ofthe channel bars. When the plunger is raised above the water surface inthe tank, air is trapped in these spaces 7 and some of this air iscarried beneath the water when the plunger descends, so that the presentplunger functions similarly to the so-called vacuum plunger-s.

From the foregoing, I believe that those skilled in the art will readilyunderstand the invention, and it is obvious that changes may be made inthe details illustrated without departing from the spirit of theinvention as expressed in the following claims.

What I claim and desire to secure by Letters Patent is:

1. A washing machine pounder comprising a series of parallel arrangedopen-endzed inverted channel-shaped bar s, liner bars substantiallyfilling the channels of the channel-shaped bars and having their sidewalls spaced from the inner surfaces of the side walls of thechannel-shaped bars, and means for securing said channelshaped barstogether and said liner bars to the channel-shaped bars, the lower edgesof the side walls of said bars having rounded surfaces to preventtearing of materials being washed.

2. A washing machine pounder comprising a series of parallel arrangedsheet metal inverted channel-shaped bars having diverging side walls,liner bars arranged, in the channels of the channel-shaped bars andhaving parallel side surfaces spaced from the inner surfaces of the sidewalls of the channel-shaped bars .to provide recesses, longitudinal barsarranged. at right angles to V 5 2 in which the edges of said side Wallsof the channel-shaped bars and means connect ing said longitudinal bars,channel-shaped bars and liner bars together.

3. A'pounder ofthe kind defined by claim In testimony whereof I hereuntoaffix my signature in the presence of tWo Witnesses.
